OFFICE 7 AIR oonmrf izzii arrana'rus A matrix stills: was-u -1- This invention relates to apparatus for conditioning or cooling air, and has for one of its obiects'the provision of such a device which is self-contained and is adaptable for use in the home or ofllce.

Another object of the invention is the provision of a cooling system of the character referred to which comprises a cabinet housing a refrigerating compartment fromwhich cold water is pumped and circulated through apair of opthe said radiators being at opposite ends of an enclosed compartment in which a fan rotates to draw warm or hot air through one of the said radiators and expell same through the other of said radiators, thus subjectingthe said air to a double cooling action.

A further object of the invention is to so tilt or incline the radiators that the incoming and outgoing air will pass therethrough at the most advantageous angle.

Another object is. to produce a device of the characterdescribed in which the maximum simplicity or construction and operation is secured.

Other objects and advantages will appear as the nature. of the. improvements is better understood, the invention consisting substantially in the novel arrangement and co-relation of parts herein fully described, and illustrated in the accompanying drawing, and then finally pointed out and specifically defined and indicated in th appended claims.

The disclosure made the basis of exemplifying the present inventive concept suggests a practical embodiment thereof, but the invention is not to be restricted to the, exact, details of this disclosure, and the latter therefore, is to be understood from an illustrative rather than a water compartment and a second pipe leads up-- wardly from the pump and is in direct communication with one of the inclined radiators formed 3 Claim!- (Cl. 62-134) l compartment; Thesaid radiator is connected by a pipe line to a second radiator at the opposite end of the air conditioning compartment and a water return pipe leads downwardly from the said second radiator to the water compartment.

The type of radiators employed is preferably of the screen or lattice type, spaces between the pipes thereof sloping upwardly and outwardly so that no direct blast of cold airwill strike anypositely, disposed grill or lattice like radiators,

one in the room where the device is located.

In the drawing the single figure is a perspective view, mostly diagrammatic, of a preferred embodiment of the invention with the front wall thereof broken away to show the interior. In the said figure the numeral 1 denotes a cabinet having a bottom wall or base 2 upon which is mounted an electric motor 3. A liquefying unit 4 of any suitable type forthe purpose is operated by a belt and pulley drive I from the motor 3. The refrigeration coil 6, of the liquefylngvunit 4 extends upwardly through a floor l of a water containing compartment I. A drain cock 9 may be provided near the bottom and at one end of the said water compartment 8. Water may be admitted to the compartment through an inlet 9a.

A plate It covers the compartment 8 and provides a floor for a third compartment l I in which is suitably located a pump [2 having a suction pipe I3 extending downwardly for a suitable dis-. 'tance into the watercompartment 8. The said pump is driven from a thermostatically controlled electric motor H. electrically connected to a thermostat i5 secured tov one. wall of the cabinet and which may .be set so that the motor operates at any desired external temperature. The drive means. between the motor and pump may comprise any suitable means, such as for instancea belt and pulley drive it. The motor and pump compartment is closed at the top by a plate II which forms the floor or base for an air cooling or conditioning compartment l8.

Secured to the base plate I1 is a pair of uprights I! terminating in bearings 20 in which is journalled a shaft 2| supporting a fan 22. The said shaft 2| and fan 22 are driven by means of a belt 23 encompassing a pulley 24 on the shaft 2i and a pulley 25 on the motor shaft 26. The top of the compartment I8 is closed by a plate or top wall 21.

A pair of radiators 28 and 29 are positioned at the left and right, respectively, of thecompartment l8. The said radiators are preferably of the grid .or lattice type and are placed in inat one end of the uppermost or air conditioning clined position so that the spaces or openings 30 3 I between pipes or tubes 32 and 32 or the respective radiators extend upwardly and outwardly of the compartment l8. A pipe 34 extends upwardly from the pump l2 and leads into the radiator 28 which is connected'to radiator 28 by a pipe 35. A return pipe 38 leads from radiator 29 to the water tank or compartment/8;

In operation, when the motor I4 is running, the belt 23 will drive the fan 22 and air will be sucked into the'compartment l8 through either radiator 28 or 29 depending upon the direction of rotation of the fan 22. In the present instance, air is shown by arrows A as entering the compartment through the openings 3| in the radiator 29 and leaving as indicated by arrows B through the openings 30 in radiator 28.

It will be seen that due to the direction of slope of the openings 30 and 3| in the radiators, no air is directly drawn from below and none is blown downwardly, thus avoiding all possibilities of drafts. It will further be seen that the air leaving the radiator is thoroughly cooled as it is first cooled on the entrance side by direct contact with the radiator pipes of the device, is further cooled in the chamber l8 and finally by contacting the pipes on the exit side.

From the foregoing, it will be seen that the device herein described and illustrated is highly efficient, will thoroughly cool the air and will cause no undue drafts but will provide a steady circulation of cool air wherever used.

It is apparent that the illustration shown above has been given by wayoi illustration and not by way of limitation and that the above structure is subject to wide variations and modifications. without departing from the scope or intent of the present invention. All of such variations and modifications are to be included within the scope of the present invention.

What is claimed is:

1. In an air conditioning and cooling device. a cabinet, a motor driven liqueiying unit in the said cabinet, a water compartment, said liquefying unit comprising an evaporator coil extendin into the water compartment, an air cooling compartment at the top of the cabinet, a pair 01' oppositely disposed interconnected radiators forming walls for said cooling compartment, said radiators comprising spaced apart pipes which slant upwardly and outwardly from the bottom of the air cooling compartment, a water circulating system connecting the water chamber to the radiators, and a fan for drawing air through the spaces between the pipes of 'one radiator and expelling same through the spaces of the opposite radiator.

2. An air conditioning and cooling device, comprising a cabinet, a lowermost compartment in said cabinet, a water above the lowermost compartment, a third compartment above the water containing compartment, an air cooling compartment abovethe last mentioned compartment, a motor driven liqueiying unit in the lowermost compartment, said liquefying unit comprising an evaporator coil extending into the water compartment, a water circulating system comprising a pump in the third compartment, a motor operatively connected to said pump for driving same, a pipe extending from the pump into the water chamber, a pair of interconnected inclined radiators disposedat opposite sides of the air cooling compartment, said radiators comprising spaced apart pipes which slant upwardly and outwardly from the bottom of the air cooling compartment, a Pipe connecting the pump to one'oi said radiators, a return pipe extending from the other of said radiators to the water compartment and a fan in theair cooling chamber driven by the pump motor for drawing air to be cooled through the spaces between the pipes of one radiator and expelling same through the spaces of the opposite radiator.
